MOBGESTERN, GF METUCHEN, NEW JERSEY, ASSIGNR "EO THE VESTEB-N UNON TELE-GRAPH CGMAJY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK METALLIC BATTERY SUPIELY Ftl'v GRUNDEDSOURCES Application filed September This invention relates to a method of obtaining nietallic battery su eply for nieta-llic telegraph circuits freni a grounded source. ln particular, it comprise ineans for supplying inetallic batter y #ni the grounded battery Wl ich is found all telegraph offices of any appreciable size through the niediuin of either very sinall storage batteries or large capacity condensers.

Another object of the invention is to ob tain battery for a large nuniber of metallic telegraph circuits frein a coninion ground-ed source.

ther objects of the invention are to obtain nietallic battery supply fr ni a. grounded source for a telegraph repeater, or for inetallic systein of the superposed type, such as that described, for example, in niy copending application Serial No. 258,949 tiled March 3, 1928 for superimposed telegraph circuits.

The fundamental principles of the invention are described hereinafter in connection with two specic arrangements for obtaining the metallic battery supply by the operation of rela 7s designed to connect large capacity condensers alternately to the grounded source, for charging purposes, and to the inetallic line into which the condensers discharge.

t is obvious, however, that iny invention is capable of enibodinient in a variety of specific foi-nis, which will readily suggest thernselves to one skilled in the art.

Referring to the drawings:

Fig. 1 illustrates the invention applied to a inetallic telegraph circuit, in which the inetallic battery supply is represented as a pair of condenser-s, each controlled by a pair of polar relays, for connection to the grounded charging source, and alternately to the inetallic line conductors independently f the grounded source. Y

Iig. 2 shows a svstein differingfroin that of 1 in that the pairs of polar relays are replaced by polar relays having two sets of contacts and a tongue divided into two sections insulated froin each other.

'lhe condensers 5 and 6 are arranged for connection to grounded battery for charging, or for connection to the line conductors by Way of the contacts of transmitter 15.

The charging circuit for condenser 5 is established from grounded generator or battery 16 through the left hand contacts of -the relays 1v and 2. 'iChat is, the charging circuit for condenser 5 entends frein the negative pole of grounded generator 16 through left hand contact 9 and tongue of relay 2, through condenser 5, and thence by Way of tongue 4-1 and'left hand contact 7 of relay l, tcground.

The charging circuit for condenser 6 eX- 'ends frein the positive polegof grounded 'enerator or battery 16 by Way of left hand ,ontact 19 and tongue 4A of relay Ll, through condenser 6, thence by Way of tongue 43 and left hand'contaot 17 of relay 3 'to ground.

lVhen the tongues of all four relays are on their right hand contacts a discharge circuit is prepared freni conductor 11 and terminal A1 by Way of each vof two paths, one of vvhich extends through contact 18 and tongue 43 of relay 3, condenser 6 and tongue 44@ of relay el to the contact 20 of relay 4 and thence through the previously -traced path including conductoi 29, coils 2l and 22 of relays 1 and 2, and conductor 26 to Contact 13 of the transmitter 15.

The other path froin line conductor 11 and terminal A1 extends through conductor Ll0, contact 8 and tongue 11 of relay 1', through condenser 5 and tongue 42 of relay 2 to the contact 10 of relay 2, and thence through the previously-traced path including conductor 30, coils 24 and 23 of relays 4 and 3, and conductor 27 to the contact 14 of transmitter 15.

t is apparent that the position of tongue 12 of transmitter 15 determines `which of the condensers 5 and 6 shall be connected between the terminals A and A1 and line conductors l and 11. When the tongue 12 is on its left hand contact and the relays are on their right hand contacts, condenser 6 is connected betweenline conductors 10 and 11 `by way of the coils 21 and 22 of relays 1 and 2. vWhen the tongue 12 of transmitter 15 is -on its right hand contact and the relays are on their right hand contacts, condenser is connected between .line conductors and 11, or their terminals A and A1, by way of the coils and 24 of relays 3 and 4.

lt may be noted that normally condensers 5 and 6 are tied together at the common point Al when the relays are lon their right hand contacts, the other terminals of the condensers being connected through vthe relay coils to the aternatecontacts 1,3 and 14 of transmitter 15. TWhen the control relays 1 and 2 operate, however, the connection from the common terminal to condenser 5 is opened at Contact 8 of relay 1 and a-connection to ground by way of Contact 7 is substituted. Through the operation of relay 2 the other terminal of condenser 5 is disconnected from the transmitter contact 14, and a charging circuit is completed to negative pole of grounded battery 16. However, as soon as ythe tongue of the transmitter leaves its contact 13, the ground connection on condenser 5 is removed, and the connections to common terminal A1 I. and to the transmitter contact are restored by the action of the biasing coils 31 and 32, thus applying minus potential to the right hand transmitter contact 14 and preparing a discharge circuit for condenser 5 to line.

In the same way, operation of relays 3 and 4 shifts the connections of condenser 6 from the common point A1 and contact 13,and applies ground to condenser 6 at contact 17 and battery at contact 19 in order to charge the condenser from the grounded source 16. As soon as the tongue 12 of transmitter 15 leaves its right hand contact, the ground is removed from condenser 6, the connection to common point A1 is restored by the biasing coils 33 and 34, and plus potential is applied to the left hand contact of the transmitter 15 to prepare a `discharge circuit from condenser 6 to line.

In Fig. 2, the pairs of polar relays 1, 2 and 3, 4 are replaced by single polar relays 50 and 60, each having two sets of contacts and a tongue. divided into two sections insulated from each other. In order .that it shall be apparent that the parts of these relays 50 and 60 perform the same functions that are performed by the pairs of relays of Fig. 1, the same numerals are used to designate corresponding elements as in Figs. 1 and 2.

Thus the relay 50, having biasing winding 52 and operating winding 51, is provided with two tongue sections 4l and 42 insulated from each other and designed to perform the same functions respectively as tongue 41 of relay 1 and tongue 42 of relay 2 in Fig. 1.

The left and right handcontacts for tongue section 41 of relay 50 are indicated by the numerals 7 and 8; the left and right hand contacts of tongue section 42 of relay 50 are indicated by the numerals 9 and 10. Similarly, relay 60, having a biasing winding 62 and an operating winding 61, is provided with left and right hand contacts 17 and 18 for tonguelsection 43, and left and right hand contacts 19 and 2O for tongue section 44.

Thegrounded source 16 in Fig. 2 and conductors 29,. and 40, line conductors 10 and 11 and transmitter 15 with its tongue 12 and left Aand right hand contacts 13 and 14, .correspond to the elements designated by the same numbers in Fig. 1. Y

The charging circuits for condensers 5 and 6 of Fig. 2 may be traced as follows: for condenser 5, from negative pole of grounded source 16 through left hand contact 9 and tongue 42 of relay 50, through condenser 5, tongue 41 and left hand contact 7 of relay 50 to ground; for condenser 6, from positive pole of grounded source 16 through left hand contact 19 and tongue 44 of relay 60, through condenser 6, tongue 43 and lleft hand contact 17 of relay 60 to ground.

The discharging circuit for condenser 6 to line extends from line conductor 10 at terminal A, through tongue 12 and left hand contact 13 of transmitter 15, conductor 26 and coil 51 of relay 50, conductor 29, right hand contact 2O and tongue 44 of relay 60, through condenser 6, .thence through tongue 43 and right hand contact 18 of relay 60 to `terminal A1 and line conductor 11.

The discharging circuit for condenser 5 to line extends from line conductor 10 at terminal A, through tongue 12 and right hand contact 14 of transmitter 15, conductor 27 4and coil 6l of relay 60, conductor 30, right hand contact 1() and tongue 42 of relay 50 through condenser 5, thence through tongue 41 and contact 8 of relay 50 and conductor to terminal A1 and line conductor 11.

The biasing circuit for relays and 60 extends from grounded battery and resistance through coils 62 and 52 in series to ground.

The operation of the circuit -of Fig. 1 is as follows:

It will be assumed that the condensers 5 and 6 are charged, to start with. lVlien charged the biasing currents will cause the relays 1, 2, 3 and 4 to return to their right hand contacts. When all the relays are on their right hand contacts, plus andininus po- Cil Cil

As soon as the tongue of the transmitting device leaves its lett hand contact e tongues of relays 1 and 2 will be moved by their biasing coils to their right hand contacts, thus putting potential on the right 'iand contact 14 of the transmitting device.

This cycle of operations is repeated in accordance with the movements ci the tongue ot the transmitter 15.

lt will be observed that the condensers will be entirely tree of ground, When their control relays are on their right hand contacts, and there Will be no ground at all on the metallic system from the battery supply although the energy i'ior transmitting a telegraph signal caiie originally tr in a grounded source oft potential.

ln Fig. 2, when the transmitter is on its right hand contact, minus curre` t Will be sent i iand contact, the biasing circuit ot relay will become iptective to put plus poten iai on the lett hand contact or the transmitter'.

When the transmitter moves to its left hand contact, plus current will be sent to line relay o@ will operate to put condenser 5 on charge. As soon as the transn itter leaves its left hand contact, the biasing circuit ot relay Will becon e etlective to put minus potential on the right hand contact of the transinitter.

Any fast high quality relay can be use-c lor the control relays in this device. Either biased polar relays or spring biased high grade single current relays can be employed.

In practice special tongue and spring contl GO tacts would be used to shorten the travel time of the control relays so that even it continuity preserving devices Were used for the transmitter there would be little loss of signal elliciency due to the time consumed by the control relay in passing from one contact to the other.

Numerous variations are possible in the systems disclosed without departure from the spirit ot the invention.

F ig. 1, (or Fig. 2) for example, may be considered either a single, independent Inetallic telegraph circuit, or else one circuit of a plurality of telegraph circuits each provided With c-ondensers (or small storage batteries) charged from a common source 16. ln tl is case, it is obvious that duplicating the circuits of the ligure Would serve no useful purpose. lt may be understood that each metallic telegraph circuit Will be supplied with its oivn individual condensers, and control relays for connecting the condensers alternately to the common grounded source and to the individual lines into Which the condensers are to discharge.

rllhe transmitter 15, represented diagraminatically by tongue and contacts may, obviously, term part of a telegraph repeater or it may be the usual terminal transmitter.
